Mercedes-Benz
Mercedes-Benz (), commonly referred to as Mercedes and sometimes as Benz, is a German luxury and commercial vehicle automotive brand established in 1926. Mercedes-Benz AG (a Mercedes-Benz Group subsidiary established in 2019) is headquartered in Stuttgart, Baden-Württemberg, Germany. Mercedes-Benz AG produces consumer luxury vehicles and commercial vehicles badged as Mercedes-Benz. From November 2019 onwards, Mercedes-Benz-badged heavy commercial vehicles (trucks and buses) are managed by Daimler Truck, a former part of the Mercedes-Benz Group turned into an independent company in late 2021. In 2018, Mercedes-Benz was the largest brand of premium vehicles in the world, having sold 2.31 million passenger cars. The brand's origins lie in Daimler-Motoren-Gesellschaft's 1901 Mercedes and Carl Benz's 1886 Benz Patent-Motorwagen, which is widely regarded as the first internal combustion engine in a self-propelled automobile. The slogan for the brand is "the best or nothing". Hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compression Ratio
The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values. A fundamental specification for such engines, it is measured two ways: the static compression ratio, calculated based on the relative volumes of the combustion chamber and the cylinder when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gasses entering and exiting the cylinder during the compression phase. Effect and typical ratios A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to ...

Mercedes-Benz W463
The Mercedes-Benz G-Class, sometimes colloquially called the G-Wagen (as an abbreviation of Geländewagen) is a four-wheel drive automobile manufactured by Magna Steyr (formerly Steyr-Daimler-Puch) in Austria and sold by Mercedes-Benz. Originally developed as a military off-roader, later more luxurious models were added to the line. In certain markets, it has been sold under the Puch name as Puch G until 2000. The G-Wagen is characterised by its boxy styling and body-on-frame construction. It uses three fully locking differentials, one of the few passenger car vehicles to have such a feature. Despite the introduction of an intended replacement, the unibody SUV Mercedes-Benz GL-Class in 2006, the G-Class is still in production and is one of the longest-produced vehicles in Daimler's history, with a span of years. Only the Unimog surpasses it. In 2018, Mercedes-Benz launched a technically new second generation, still with only minor design changes. The 400,000th unit was bui ...

Mercedes-Benz R129
The Mercedes-Benz R129 SL is a roadster which was produced by Mercedes-Benz from 1989 until 2001. The R129 replaced the R107 in 1989 and was in its turn replaced by the R230 SL-Class in 2002 for the 2003 model year. The R129 was offered as a two-door roadster with an automated (electro-hydraulic), fabric convertible roof; colour-matched, automated tonneau cover; and a manually detachable hardtop that could be fitted over the stored fabric convertible roof and tonneau. It was available with a variety of powertrains across its twelve-year production, including a V12 option used in the SL600. Development and launch Designed in 1984, the R129 was based on the shortened floorpan of the Mercedes-Benz W124. The new SL-class was presented at the Geneva Motor Show in March 1989, with left-hand drive sales beginning that summer and right-hand drive sales in the autumn. It came runner-up behind the Citroen XM for the European Car of the Year accolade. Models Model history Desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercedes-Benz R107
The Mercedes-Benz R107 and C107 are sports cars which were produced by Mercedes-Benz from 1971 until 1989, being the second longest single series ever produced by the automaker after the G-Class. They were sold under the SL (R107) and SLC (C107) model names as the 280 SL, 280 SLC, 300 SL, 350 SL, 350 SLC, 380 SL, 380 SLC, 420 SL, 450 SL, 450 SLC, 450 SLC 5.0, 500 SL, 500 SLC and 560 SL. The R107/SL was a two-seat car with a detachable roof. It replaced the W113 SL-Class in 1971 and was replaced by the R129 SL-Class in 1989. The predecessor W113 was notably successful in North America, with 19,440 units (40%) of 48,912 total units sold in the US. The R107 and C107 were even more focused on the American market, with specialized engines, bumper designs, headlights, and emissions management designs. The R107 and C107 sold 204,373 units in the US (68%) of 300,175 total units sold (excluding grey market sales into the US). It was the only Mercedes roadster during its entire produ ...

Mercedes-Benz W126
The Mercedes-Benz W126 is the company's internal designation for its second generation S-Class, manufactured in sedan/saloon (1979–1991) and coupé (1981–1990) models, succeeding the company's W116 range. Mercedes introduced the 2-door C126 coupé model, marketed as the SEC, in September 1981. This generation was the first S-Class to have separate chassis codes for standard and long wheelbases (W126 and V126) and for coupé (C126). The long 12-year production (1979–1991) resulted in 818,063 sedans/saloons and 74,060 coupés being built, totalling 892,123. W126 is so far the most successful and the longest in production for S-Class. History After the debut of W116 S-Class in 1972, Mercedes-Benz began preparing for the next generation S-Class in October 1973. The project, code-named "Project W126", aimed to provide an improved ride, better handling, and improved fuel efficiency. The oil crisis of 1973 and increasingly stringent emission and safety regulations in the Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercedes-Benz W124
The Mercedes-Benz W124 is a range of mid-size cars made by Daimler-Benz from 1984 to 1997. The range included numerous body configurations, and though collectively referred to as the W-124, official internal chassis designations varied by body style: saloon (W 124); estate (S 124); coupé (C 124); cabriolet (A 124); limousine (V 124); rolling chassis (F 124); and long-wheelbase rolling chassis (VF 124). From 1993, the 124 series was officially marketed as the Mercedes-Benz E-Class, E-Class. The W 124 followed the Mercedes-Benz W123, 123 series from 1984 and was succeeded by the Mercedes-Benz E-Class (W210), W 210 E-Class (saloons, estates, rolling chassis) after 1995, and the Mercedes-Benz C208, C 208 CLK-Class (coupés, and cabriolets) in 1997. In North America, the W124 was launched in early November 1985 as a 1986 model and marketed through the 1995 model year. Series production began at the beginning of November 1984, with press presen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octane Rating
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates gasoline's capability against compression. Whether or not a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression gasoline engines, which may yield higher power for these engines. Such higher power comes from the fuel's higher compression by the engine design, and not directly from the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (also called compression-ignition engines) do not compress the fue ...

Ignition System
An ignition system generates a spark or heats an electrode to a high temperature to ignite a fuel-air mixture in spark ignition internal combustion engines, oil-fired and gas-fired boilers, rocket engines, etc. The widest application for spark ignition internal combustion engines is in petrol (gasoline) road vehicles such as cars and motorcycles. Compression ignition Diesel engines ignite the fuel-air mixture by the heat of compression and do not need a spark. They usually have glowplugs that preheat the combustion chamber to allow starting in cold weather. Other engines may use a flame, or a heated tube, for ignition. While this was common for very early engines it is now rare. The first electric spark ignition was probably Alessandro Volta's toy electric pistol from the 1780s. Siegfried Marcus patented his "Electrical igniting device for gas engines" on 7 October 1884. History Magneto systems The simplest form of spark ignition is that using a magneto. The engine spins ...

Starter Motor
A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power. Starters can be electric motor, electric, pneumatic motor, pneumatic, or hydraulic motor, hydraulic. The starter can also be another internal-combustion engine in the case, for instance, of very large engines, or diesel engines in agricultural or excavation applications. Internal combustion engines are feedback systems, which, once started, rely on the inertia from each cycle to initiate the next cycle. In a four-stroke engine, the third stroke releases energy from the fuel, powering the fourth (exhaust) stroke and also the first two (intake, compression) strokes of the next cycle, as well as powering the engine's external load. To start the first cycle at the beginning of any particular session, the first two strokes must be powered in some other way than from the engine itself. The starte ...

Engine Cooling
Internal combustion engine cooling uses either air or liquid to remove the waste heat from an internal combustion engine. For small or special purpose engines, cooling using air from the atmosphere makes for a lightweight and relatively simple system. Watercraft can use water directly from the surrounding environment to cool their engines. For water-cooled engines on aircraft and surface vehicles, waste heat is transferred from a closed loop of water pumped through the engine to the surrounding atmosphere by a radiator. Water has a higher heat capacity than air, and can thus move heat more quickly away from the engine, but a radiator and pumping system add weight, complexity, and cost. Higher-power engines generate more waste heat, but can move more weight, meaning they are generally water-cooled. Radial engines allow air to flow around each cylinder directly, giving them an advantage for air cooling over straight engines, flat engines, and V engines. Rotary engines have a ...

Motor Oil
Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines. They typically consist of base oils enhanced with various additives, particularly antiwear additives, detergents, dispersants, and, for multi-grade oils, viscosity index improvers. The main function of motor oil is to reduce friction and wear on moving parts and to clean the engine from sludge (one of the functions of dispersants) and varnish (detergents). It also neutralizes acids that originate from fuel and from oxidation of the lubricant (detergents), improves sealing of piston rings, and cools the engine by carrying heat away from moving parts. In addition to the aforementioned basic constituents, almost all lubricating oils contain corrosion and oxidation inhibitors. Motor oil may be composed of only a lubricant base stock in the case of non- detergent oil, or a lubricant base stock plus additives to improve the oil's detergency, extreme p ...
